## About

## What it does
Readability Score analyzes plain text and returns readability metrics you can use to judge how easy a document is to read. Send raw text in the `body.text` field, and choose `body.language` as `english` or `german` to select the scoring algorithm.

The response includes text statistics such as `words`, `sentences`, `characters`, `paragraphs`, estimated `reading_time`, estimated `speaking_time`, and average length measures like `avg_word_length`, `avg_sentence_length`, and `avg_paragraph_length`. It also returns a readability result object for the chosen language: `flesh_kincaid_reading_ease` for English or `wiener_sachtextformel` for German.

Use Readability Score to review help articles, product copy, onboarding guides, or any user-facing text before publication. The returned `class`, `level`, `score`, `label`, and `class_label` make it easier to compare drafts, enforce content standards, or surface content that is too dense for your audience.
